Macintosh SE Video Issue (single vertical line)

I'm having an issue with my Mac SE where the video goes to a single vertical line (1 pixel thick) after about 20 minutes of use. If I turn it off, and wait about 5 seconds, it comes back, but I really don't like switching it off like that (as it's really not good for the power supply). The analog board looks good, but I don't have the proper equipment to check the capacitors. Does anyone know what's going on? Is it the capacitors? And if so, does anyone have a list of the replacements I'm going to need?

Bad connectors.

Bad connectors.
Check the contacts between the digital and the analog boards.

Check C15 and the yoke connector

Most likely it's C15, the 3.9uF NON-POLARIZED cap. You should also check the yoke connector P1; those pins often develop cracks where soldered.

Is it possible for you to post a picture of the component so I know where, and what I'm looking for? I'm still really new at this.
